Swiss Knife

In 2024 we published an in-house tool that we used only internal for years.

It can help you with various everyday tasks that are outside Rector's scope, but are connected with upgrades and code quality.

Swiss Knife package is scoped and downgraded. It requires PHP 7.2+ and can be installed on any legacy project.

Install with Composer:

composer require rector/swiss-knife --dev

Features

It helps you to:

finalize all classes except entities, mocked classes, classes with children, YAML-defined etc.
privatize class constant, that are never used outside the class
detect commented code creep
convert random namespaces to PSR-4 - updates composer.json, class names and use imports
spot accidental git conflicts in CI
turn any JSON file to nice and human-readable format
search all PHP files with quick regex
generate Symfony 5.3 configs
split huge Symfony configs to per-package in /packages/ folder
spot fake-traits

...and more
